“…A large and growing body of research highlights the roles of frontal, temporal, limbic, and paralimbic brain circuits for promoting and regulating aggression, antisocial behavior, and disinhibited behavior more generally. This work has provided some insight into the deficits exhibited by individuals with a propensity for even the most extreme violence (Bannon, Salis, & O'Leary, 2015;Rosell & Siever, 2015;Smith, Smith, & Misquitta, 2016). Some of the earliest functional neuroimaging studies that examined homicide offenders concluded that murderers were characterized by reduced activity in brain areas including lateral and medial prefrontal cortex (Raine, Buchsbaum, & LaCasse, 1997;Raine et al, 1994;Raine et al, 1998), as well as medial temporal regions, including the amygdala, and extended temporal and parietal regions (Raine et al, 1997;Raine et al, 1998).…”
